Answer #1

Here we calculate the partition function, molar translational
internal energy, and molar translational entropy of a monatomic
gas. The single particle translational partition function is
qtrans=VΛ3) where Λ is the thermal wavelength and teh entropy is
given by the Sackur-Tetrode equation
S=N*kB*ln((qtrans*e^5/2)/N).

Natural Gas (1 mol/s) composed of 85 mol% methane, 8 mole%
ethane and 7 mol% CO2 is
used to generate heat in a boiler. The fuel is fed to the boiler
with 25% excess air that has a relative
humidity of 35%. Both natural gas and humid air are fed at 250C.
Heat from the combustion is
transferred to liquid water that enters the heat exchanger as a
liquid at 250C and leaves as a vapor at 1
bar and...

An industrial requires 1000kg/hr. of saturated steam vapor at
500kpa natural gas combustion products (use air properties) at

What does the entropy change of the combustion gases?
What is the change in the entropy of the boiling water?

Methane gas (CH4) at 25 °C is burned steadily with
dry air, which enters a combustion chamber of a natural gas boiler
in a small power plant at 17 °C. The volumetric analysis of the
flue gas on a dry basis is 5.2% carbon dioxide, 0.33% carbon
monoxide, 11.24% diatomic oxygen, and 83.23% diatomic nitrogen. The
flue gas leaves at 700 K.
